Abstract

See full text

A method and system for magnetic measurement of elongation of a fastener includes a means for providing a magnetic field gradient along an axis of the fastener, such as one or more permanent magnets. A magnetic sensor is mounted in the fastener in the magnetic field gradient. Magnetic field measurements taken by the magnetic sensor are dependent on a length of the fastener and are sufficiently sensitive to monitor loading during a service life of the fastener. The fastener may be equipped with a signal reader and a data interface for offloading measurement values.
